    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 cea%M3  
    e%u1O -*  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: q>?uB4>^  
    enableservice('AutomationServer', true) ]FL=E3U  
    enableservice('AutomationServer') 7J.alV4`/  
    _/]4:("  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 2:Zb'Mj

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: grp1nWAs  
    1. 在FRED脚本编辑界面找到参考. wk' |gI[W  
    2. 找到Matlab Automation Server Type Library Vd1.g{yPV  
    3. 将名字改为MLAPP t,)` Zu$

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 BRhAL1

    5. 使用PutWorkspaceData发送照度数据到Matlab Hw-,sze j"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 rd vq(\A  
    7. 用Matlab画出照度数据 8*k#T\
